Overview

Heppia lutosa is a species of jelly lichen in the family Porocyphaceae. The species forms small scaly lobes up to 10 mm across that are attached to the substrate by a central point, with a dark olive upper surface and a pale to reddish-brown underside. It occurs in Africa, Europe, and North America.

Heppia lutosa, a crustose lichen species, faces significant threats from habitat degradation and loss due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its substrate. Climate change and urbanization further threaten the specialized microhabitats this species requires for survival.
